To all whom it may concern:

Be it known that I, CHARLES J. HARTLEY, a citizen of the United States,residing at Decatur, Macon county, Illinois, have 1nvented certain newand useful Improvements in Grain-Conveyors; and I do hereby declare thefollowin to be a full, clear, and exact description o the invention,such as will enable others skilled in the art to' which it appertains tomake and use the same..

, This invention relates to certain improvements in conveyers for grainand the like; and the objects and nature of my invention will be readilyunderstood by those skilled in the art in the light of the ollowingdescription of the accompanyin drawings illustrating what I now consi ermy preferred embodiment from among other forms and arrangements withinthe spirit and sco e of my invention. l

n object of the invention is to simplify mechanism for handling grain,or other material, and delivering the same as desired alternately atdiierent points, and to reduce the number of working parts to a minimum.

A further object of the invention is to provide certain improvements inarrangements of parts and combinations of elements whereby an improvedand highly eicient grain conveyer will be produce 'Ihe inventionconsists in certain novel features in construction and in combinationsand arrangements as more. fully and particularly set forth hereinafter.

Referring to the accom anying drawings: 'Figure 1, isa longitudinasection, the parts being adjustedto deliver the grain at the far orright hand end of the conveyer. Fig. 2, is a side elevation, parts beingbroken away, the elements bein adjusted to deliver the grain at the nearor eft hand end of the conveyer. Fig. `3 is a detail view of theshut-olii' valve.

In the drawings, 1, isa horizontally elongated tubular casing for ascrew or auger'- conveyer. This casing is provided with a top receivinghopper 2, openin thereinto and arranged at one end thereo and with abottom discharge opening or chute 3, at its near end below the hopper,and with another botom discharge o ening or chute 4, at its opposite orfar end). The bottom discharge opening 3, is removed a distance from thea jacent end wall of the casing thereby having what might be termed aocket below the hopper and between sai end wall and adjacent bottomopening 3. To move the grain from this pocket and longitudiv nally4within the casing and toward the opposite end thereof, I provide ascrew conveyer or auger section 5, longitudinally occupying the casingfrom opening 3 to said adjacent end wall. The spiral b ade of the screwor auger conveyor section is rigid with its longltudinal hollow shaft 6,at its inner free end notched or otherwise formed to constitute a clutchmember 7, and reduced and fitted at its outer end 9, to rotate in thejournal box 8, in the end wall of the casing and elongated to extendoutwardly beyond said journal box to rigidly receive the exterior screwconveyer actuatin pulley or gear 10. The screw section 5, is ieldagainst undue longitudinal movement within the casing by the hub of thepulley 10, engaging the outer end of the journal box 8, and b theintermediate shoulder of the screw s aft engaging. the inner end of saidjournal box.

11, is a rotary spiral, screw or auger conveyer section arrangedlongitudinally with-` in the casing and occupying the remainder of thecasin from the screw section 5, to the far end ischarge 4, anddesi ed tocooperate with screw section 5, in orcing the grain from the hopper tothe far end discharge 4. This screw section 11, is rotated or actuatedthrough the medium of screw section 5, and is capable of` longitudinalshifting or sliding movement within the casing into and from operativeposition and into and from operative or driving connection with saidsection 5, according to whether the grain is to be discharged throughopening 4, or opening 3. To pery mit this longitudinal movement, screwsection l1, is in length less than the distance from screw section 5, tothe far end wall of the casing, and the shaft 12, of said section 11, isprovided with a longitudinal elongated end extension 13, passing throu hand beyond and mounted to rotate in an longitudinally through thejournal box 14, of the far end of the casing, and at its opposite endwith a longitudinal elongated end extension 15, extending longitudinallythrough and beyond the hollow shaft 6, 9,y

ofthe screw section 5. The end extension 15, is capable of slidinglongitudinally withslide j in the shaft section 6, 9, and said shaftsec` tion is capable of rotating freely oni said' end extension 15. Y

The screw section 11, is provided with a 4notched (or otherwise formed)clutch mechanism 1 6 ri id therewith and adapted to mesh wlth c utchmember 7, to lock the screw section 11, to rotation with the screwAsection 5. The clutch member 16, (in the specific example' illustrated)is fixed on the innerend of end extension 15, adjacent to the end ofshaft 12, and between said clutch member and said shaft end is looselyhung the upper end of radial arm y17, of a norl interlocked and thescrew section 11, forming a continuation of screwhsection 5, and acrosslthe valve and discharge opening 3. When' the parts are in this relation,the grain received through the hopper, will be orced by the screwsections 5, 11, (acting as a single auger or conveyer) throughout thelength of the casing to the discharge openen it is desired to dischargethe grain through openin 3, the screw section 11,

through the me ium of either shaft end extension 13, 15,'is movedlongitudinally of the casing toward and across the opening 4' therebyseparating the clutch members an throwing section 11, out of driving ar,and' moving the valve 18, inwardly of t e casin and thereby uncoveringthe opening 3, an removing the section 1l, from operatlve positionbetween the hopper and the opening 3. When the partsy are thus arranged,the grain receivedl through the hopper will drop through opening 3 andthe grain droppin into the pocket will be forced therefrom an intoopenin 3, by the `screw section 5. When 1t is esired to close opening 3,and discharge through opening 4, the section 11, is again forcedongitudinally of the casing to its former operative position asshown byFig. 1`,\of the drawings.

f so desired, the shaft 12 can be longitudinally hollow and the en 15,formed by straight round metal bars headed at their outer ends and havintheir inner ends inserted in the shaft en s and xed by cross pins. e

This invention is uliarly adapted for use in connection wit grainseparators and threshing machines, but I do not wish to limit myinvention to use in such .connec tions nor to emplo ent for handlinggrain.

lIt is evident tA various cha es and variations might be resorted to wiout deoperatively extensions 13,-

parting from the spirit andv scope of my invention and henceI do notwish to i myself to the exact constructions-shown. Y What I claim is':--p v 1.

3. Inconveyers, a casing having-severalv spaced discharge openings, ascrew conveyer in said casing, said conveyercomprisin a lon itudinallmovable section provl ed with said discharge openings.

4. In conveyers, a sectional screw conveyer, the shaft of one sectionbeing extended and telescoping the other section and means foralternately operatively connecting and disconnecting said sections. l

5. In conve ers, a screw conveyer comprising separa le sections, theshaft of one section being extended and slidably telescopingthe othersection, means for applying power to one section, and means .forconnecting and disconnecting said sections.
